Vitallium2000铸造支架义齿、纯钛支架义齿及钴铬合金支架义齿在义齿修复中的效果比较

Efficiency comparisons among Vitallium2000 casting denture,titanium denture and cobalt-chromium alloy denture in denture restoration

目的比较Vitallium2000铸造支架义齿、纯钛支架义齿与钴铬合金支架义齿在义齿修复中的效果。方法将150例义齿修复患者按修复支架材料分为3组,即Vitallium2000组(Vitallium2000铸造支架义齿)、纯钛组(纯钛支架义齿)及钴铬合金组(钴铬合金铸造义齿),每组50例。比较3组义齿修复效果、咀嚼效率及修复满意度。结果Vitallium2000组1、2年口腔黏膜炎症发生率分别0、2.00%,均显著低于纯钛组12.00%、16.00%及钴铬合金组22.00%、32.00%(P<0.05)。Vitallium2000组1、2年咀嚼效率高于纯钛组、钴铬合金组,差异有统计学意义(P<0.05)。Vitallium2000组义齿修复满意率96.00%,显著高于纯钛组的76.0%以及钴铬合金组的70.00%,Vitallium2000组1、2年固位力显著高于纯钛组、钴铬合金组(P<0.05)。结论与钴铬合金支架义齿、纯钛支架义齿相比,Vitallium2000铸造支架义齿具有强度高、稳固、美观性好等优势,能维持长期理想的固位力。

Objective To compare the effect of Vitallium2000 casting denture,pure titanium denture and cobalt chromium alloy denture in denture restoration.Methods Totally 150 patients with denture restoration were divided into Vitallium 2000 group,pure titanium group and the cobalt-chromium group according to the scaffold materials.The results of restoration,masticatory efficiency and satisfaction degree were compared among the three groups.Results The incidence rates of oral mucosal inflammation at 1 and 2 years after treatment was 0 and 2.00%in Vitalium 2000 group,which were significantly lower than those in pure titanium group(12.00%,16.00%)and cobalt-chromium alloy group(22.00%,32.00%)(P<0.05).The masticatory efficiency of Vitalum 2000 group at 1 and 2 years after treatment was significantly higher than that of pure titanium group and cobalt-chromium alloy group(P<0.05).The satisfactory degree of denture restoration in Vitallium 2000 group was 96.00%,which was significantly higher than 76.0%in pure titanium group and 70.00%in cobalt-chromium alloy group(P<0.05).The retention force in 1 and 2 years after treatment in Vitallium 2000 group was significantly higher than that in pure titanium group and cobalt-chromium alloy group(P<0.05).Conclusion Compared with cobalt-chromium alloy denture and titanium denture,Vitallium 2000 casting denture has the advantages of high strength,stability and good aesthetics,which can maintain the ideal retention force for a long time.
